IMPROVEMENT IN MEANS FOR PUMPING VlmlELLS.

Specification forming part of Letters Patent No. 164,756, dated June 22, 1875; application filed May 3l, 1875.

' description thereof, reference being; had to the accompanying' drawing Ina-king a part of this specification, in which-like letters indicating,` like parts- Figure l is a plan View of our invention. Fig. 2 is a side elevation of the same, and Fig. 3 is a detailed View of a part thereof.

Our invention is intended as an improvement upon the Letters Patent No. 162,406, granted to us April 20, 1875; and the nature of our invention consists in the construction and arrangement of certain devices for operating two or more independent walking-beams in different directions at the Same time, and thus counterbalance each other, as will be hereinafter more fully set forth.

A1, A2, A3,and A4 represent the four walking-beams of the pumps operating` in four different wells. B is the band-wheel or equivalent device, driven by a belt, B, from the engine. On the shaft or journal of the bandwheel B is a crank, a, connected by a pitmau,

b, with one end of the walking-beam A', the other end of said walking-beam having the pump-plunger attached to it. From the pitman end of the walking-beam A a rope or chain, d, passes around a pulley, e, and connects with braces G 4depending from the well end of the walkingfbeam A2, the two walkingbeams A1 and A2 being thus operated from the crank a in opposite directions at the same time. The crank c is further, by a pitman, f, connected with one arm of a T-shaped lever, D, pivoted as shown. The two Side arms ot' the lever D are, by rods h 71 connected with L- shaped levers E E, and the other ends of said levers are, by rods z' fi, connected with the ends of the Walking-beams A3 and A4 respectively. These two walking-beams are thus also at the same time operated from the same crank in opposite directions. The connections between the crank a and the Walking-beams a3 t4 are, as will be observed, positive, making their movement certain and reliable.

Other walking-beams may be, in like manner, connected to and operated by the same crank, thus having a series of walking-beams operated from a single crank by one motor, and every pair of beams is always moving in opposite directions, and thus balancing each other.

Having thus fully described our invention, Y

D, rods h h, L-sha-ped levers E E, rods t t', and

walking-beams A3 A4, substantially as and for the purposes herein Set forth.

In testimonyr whereof we have hereunto Set our hands.
